Der Erfindung liegt daher die Aufgabe zugrunde, sternförmig verbundene Stränge bei ETHERCAT flexibel ausbildbar zu ermöglichen.The invention is therefore based on the object of enabling star-shaped connected strands to be flexibly formed in ETHERCAT.
Erfindungsgemäß wird die Aufgabe bei dem Bussystem nach den in Anspruch 1 angegebenen Merkmalen gelöst.According to the invention, the object is achieved in the bus system according to the features specified in
Wichtige Merkmale der Erfindung bei dem ETHERCAT-Bussystem sind, dass er einen ETHERCAT-Busmaster und ETHERCAT-Busteilnehmer aufweist,
wobei ein ETHERCAT-Sternverteiler zusammen mit dem ETHERCAT-Busmaster auf derselben Leiterplatte angeordnet und/oder bestückt sind.Important features of the invention in the ETHERCAT bus system are that it has an ETHERCAT bus master and ETHERCAT bus participants,
where an ETHERCAT star distributor and the ETHERCAT bus master are arranged and/or mounted on the same circuit board.
Von Vorteil ist dabei, dass die Sterntopologie direkt auf der Leiterplatte und somit auch in Echtzeit ausführbar ist. Außerdem ist die Anordnung störungssicher. Darüber hinaus ist die Spannung auffrischbar. Durch die integrierte Ausführung auf einer einzigen Leiterplatte ist eine Echtzeit-fähige Realisierung des ETHERCAT-Busses ermöglicht.The advantage is that the star topology can be implemented directly on the circuit board, allowing it to be implemented in real time. Furthermore, the configuration is interference-free. Furthermore, the voltage can be refreshed. The integrated design on a single circuit board enables a real-time implementation of the ETHERCAT bus.
Die Flexibilität ist durch die Ausführung auf einer einzigen Leiterplatte gewährleistet, da die Bestückung der Leiterplatte flexibel ausführbar ist. Je nach Bedarf wird eine andere Bestückung ausgeführt. Somit ist eine jeweils gewünschte Variante an Sternverteiler und Busmaster bestückbar. Somit ist kein erhöhter Lagerbedarf notwendig.Flexibility is ensured by the design on a single circuit board, as the PCB assembly can be configured flexibly. Different assembly configurations can be implemented as needed. This allows for the desired star distributor and bus master configuration to be installed. This eliminates the need for increased inventory.
Bei einer vorteilhaften Ausgestaltung ist am Anschluss, insbesondere Ausgang, des Busmasters, ein Pegelwandler angeordnet, von dem Datenleitungen über zumindest eine kapazitive Trennung, insbesondere Kondensatoranordnung, zu einem weiteren Pegelwandler führen, welcher am Anschluss des Sternverteilers angeordnet und/oder angeschlossen ist. Von Vorteil ist dabei, dass trotz der Anordnung auf derselben Leiterplatte und somit geringem Abstand zwischen Busmaster und Sternverteiler eine Pegelwandlung und Pegelrückwandlung mit zwischengeordneter galvanischer Trennung ausgeführt ist.In an advantageous embodiment, a level converter is arranged at the connection, in particular the output, of the bus master. From this level converter, data lines lead via at least one capacitive isolation, in particular a capacitor arrangement, to another level converter, which is arranged and/or connected to the connection of the star distributor. The advantage here is that, despite the arrangement on the same circuit board and thus the short distance between the bus master and the star distributor, level conversion and level reconversion are implemented with intermediate galvanic isolation.
Bei einer vorteilhaften Ausgestaltung weist der Sternverteiler Ausgänge auf, wobei an jedem Ausgang ein jeweiliger weiterer Pegelwandler angeordnet und/oder angeschlossen ist, der jeweils über eine galvanische Trennung mit einem jeweiligen Steckverbinderteil verbunden ist, dass auf der Leiterplatte bestückt ist,
wobei am jeweiligen Steckverbinderteil jeweils ein Strang von mittels des ETHERCAT-Datenbusses in Reihe verbundenen Busteilnehmern anschließbar, insbesondere angeschlossen, ist. Von Vorteil ist dabei, dass wiederum Pegelwandler vorgesehen sind, so dass der Sternverteiler selbst in TTL-Logik ausführbar ist. Auf diese Weise ist eine Spannungsauffrischung in einfacher Weise im Sternverteiler ermöglicht.In an advantageous embodiment, the star distributor has outputs, wherein a respective further level converter is arranged and/or connected to each output, which is connected via a galvanic isolation to a respective connector part that is mounted on the circuit board,
A line of bus devices connected in series via the ETHERCAT data bus can be connected, in particular connected, to each connector part. It is advantageous that level converters are provided, so that the star splitter itself can be implemented in TTL logic. This allows for a simple voltage refresh in the star splitter.
Erfindungsgemäß ist die Leiterplatte von einem Gehäuse umgeben,
wobei ein Kühlkörper die Verlustwärme des Busmasters und des Sternverteilers an die Umgebung abführt. Von Vorteil ist dabei, dass ein gemeinsames Gehäuse für die Leiterplatte mit Busmaster und Sternverteiler notwendig ist. According to the invention, the circuit board is surrounded by a housing,
A heat sink dissipates the heat loss from the bus master and the star distributor to the environment. The advantage here is that a common housing is required for the circuit board, bus master, and star distributor.
Bei einer vorteilhaften Ausgestaltung ist der Busmaster mit einer Ethernet-Schnittstelle verbunden, die ebenfalls auf der Leiterplatte angeordnet ist. Von Vorteil ist dabei, dass über ETHERCAT übertragene Information über Ethernet weiter übertragbar ist.In an advantageous embodiment, the bus master is connected to an Ethernet interface, which is also located on the circuit board. This is advantageous because information transmitted via ETHERCAT can be further transmitted via Ethernet.
Erfindungsgemäß ist die Ethernet-Schnittstelle weniger weit entfernt vom Busmaster als der Sternverteiler vom Busmaster entfernt angeordnet
oder die Ethernet-Schnittstelle ist weniger weit entfernt vom Sternverteiler als der Busmaster vom Sternverteiler entfernt angeordnet. Von Vorteil ist dabei, dass keine Störungen bewirkt werden, obwohl die Ethernet-Schnittstelle sehr nahe anordenbar ist und somit Störstrahlung ausgesendet wird. Da aber Pegelumwandlung, galvanische Trennung differentielle Datenleitung sowie Spannungsauffrischung vorgesehen sind, ist der störende Einfluss beherrschbar. According to the invention, the Ethernet interface is located less far away from the bus master than the star distributor is from the bus master
or the Ethernet interface is located closer to the star junction than the bus master is to the star junction. The advantage of this is that no interference is caused, even though the Ethernet interface can be located very close and thus emits interference. However, since level conversion, galvanic isolation, differential data lines, and voltage refresh are provided, the interference is manageable.
Bei einer vorteilhaften Ausgestaltung ist der Busmaster als ein einziges Bauteil, insbesondere IC, also integrierter Schaltkreis, ausgeführt, insbesondere und auf der Leiterplatte bestückt ist. Von Vorteil ist dabei, dass eine integrierte Ausführung erreichbar ist und somit hohe Datenströme fehlerfrei oder zumindest fehlerarm übertragbar sind.In an advantageous embodiment, the bus master is implemented as a single component, in particular an IC (integrated circuit), which is mounted on the circuit board. This is advantageous because an integrated design is achievable, allowing high data streams to be transmitted error-free or at least with minimal errors.
Bei einer vorteilhaften Ausgestaltung ist der Sternverteiler als ein einziges Bauteil, insbesondere IC, also integrierter Schaltkreis, ausgeführt, insbesondere und auf der Leiterplatte bestückt ist. Von Vorteil ist dabei, dass eine kompakte Ausführung ermöglicht ist, wobei eine Massenfertigung ermöglicht ist und daher geringe Kosten pro Bauteil notwendig sind.In an advantageous embodiment, the star distributor is designed as a single component, in particular an IC (integrated circuit), which is mounted on the printed circuit board. This allows for a compact design, which allows for mass production and thus requires low costs per component.
Bei einer vorteilhaften Ausgestaltung ist der Busmaster mit einer Ethernet-Schnittstelle verbunden, die ebenfalls auf der Leiterplatte angeordnet und/oder bestückt ist. Von Vorteil ist dabei, dass eine einfache Herstellung in kompakter Weise ausführbar ist.In an advantageous embodiment, the bus master is connected to an Ethernet interface, which is also arranged and/or mounted on the circuit board. This allows for simple, compact manufacturing.
Weitere Vorteile ergeben sich aus den Unteransprüchen. Die Erfindung ist nicht auf die Merkmalskombination der Ansprüche beschränkt. Für den Fachmann ergeben sich weitere sinnvolle Kombinationsmöglichkeiten von Ansprüchen und/oder einzelnen Anspruchsmerkmalen und/oder Merkmalen der Beschreibung und/oder der Figuren, insbesondere aus der Aufgabenstellung und/oder der sich durch Vergleich mit dem Stand der Technik stellenden Aufgabe.Further advantages emerge from the dependent claims. The invention is not limited to the combination of features in the claims.

Die Erfindung wird nun anhand von schematischen Abbildungen näher erläutert:
In der
In the
Dabei ist auf einer vorzugsweise einstückig, also einteilig, ausgeführten Leiterplatte 8 eine Steuerung 1 bestückt, welche eine Ethernet-Schnittstelle aufweist und darüber hinaus mit einem auf der Leiterplatte 8 bestückten Busmaster 2 zur Datenübertragung verbunden ist.In this case, a
Zur Datenübertragung weist der Busmaster 2 einen Anschluss auf, der über einen Pegelwandler 3 und eine differentiell ausgeführte Datenleitung sowie eine kapazitive Entkopplung 9 mit einem weiteren Pegelwandler verbunden ist, der an einem Anschluss eines Sternverteilers 5 angeordnet ist.For data transmission, the
Somit werden die Signale des Busmasters nach der Umwandlung der Spannungspegel durch den Pegelwandler 3 über den differentiell ausgeführten Datenleitungen zu einer Kondensatoranordnung hingeleitet, welche die galvanische Trennung vorsieht. Gleichspannungen sind somit vom am Anschluss des Busmasters 2 angeschlossenen Pegelwandler 3 nicht zum am Anschluss des Sternverteilers 5 angeschlossenen Pegelwandler 3 durchleitbar.Thus, after the voltage levels have been converted by the
Der Spannungspegel der Wechselspannungsanteile, welche durch die Kondensatoranordnung durchgeleitet werden, wird vom Pegelwandler 3 umgewandelt und dem Sternverteiler 5 vorzugsweise als TTL-Pegel zugeführt. Auch der Busmaster ist mittels TTL-Pegelbetreibbar, so dass nur die differentielle Datenleitung einen anderen Pegel aufweist.The voltage level of the AC voltage components passing through the capacitor array is converted by the
Der Busmaster ist ein ETHERCAT-Busmaster und der Sternverteiler ist ebenfalls ein ETHERCAT-Sternverteiler. Insbesondere werden die vom Busmaster 2 kommenden Signale den weiteren Anschlüssen des Sternverteilers 5 zugeführt, deren Signale einem jeweiligen Pegelwandler 3 zugeführt werden und wiederum als differentielle Signale über eine jeweilige galvanische Entkopplung 4 zu auf der Leiterplatte 8 bestückten Steckverbinderteilen 6 geführt werden.The bus master is an ETHERCAT bus master, and the star splitter is also an ETHERCAT star splitter. In particular, the signals coming from the
Jeweils mehrere als ETHERCAT-Busteilnehmer ausgeführten Busteilnehmer 7 bilden einen seriell miteinander verbundenen jeweiligen Strang, welcher jeweils mit dem jeweiligen Steckverbinder 6 verbunden ist.A plurality of
An dem Sternverteiler 5 sind also mehrere Stränge anschließbar. In
Da der Sternverteiler 5 und der Busmaster 2 auf derselben Leiterplatte bestückt sind, ist nur ein einziges Gehäuse für den Sternverteiler 5 und den Busmaster 2 notwendig. Außerdem ist eine Entwärmung durch einen einzigen Kühlkörper ausführbar, welcher Verlustwärme des Sternverteilers 5 und Verlustwärme des Busmasters 2 an die Umgebung abführt.Since the
Da die am Sternverteiler 5 eingehenden und ausgehenden Datenleitungen galvanisch entkoppelt sind, ist eine Spannungsauffrischung innerhalb des Sternverteilers 5 bei weiteren erfindungsgemäßen Ausführungsbeispielen ausführbar.Since the incoming and outgoing data lines at the
Obwohl Busmaster 2 und Sternverteiler 5 auf derselben Leiterplatte 8 angeordnet sind, werden die Pegelwandler 3 und galvanische Entkopplungen, insbesondere kapazitive Trennungen vorgesehen. Somit sind auf der Leiterplatte andere Signalelektronikkomponenten anordenbar, deren elektromagnetische Abstrahlung zwar störend wären; da aber die galvanischen Trennungen und Pegelwandlungen negative Wirkungen von Störstrahlung verringern, sind diese anderen Signalelektronikkomponenten sehr nahe anordenbar neben den ETHERCAT-Komponenten, insbesondere Busmaster 2 und Sternverteiler 5.Although
Eine solche andere Signalelektronikkomponente ist beispielsweise auch die Ethernet-Schnittstelle. Somit ist auch diese Schnittstelle sehr nahe am Busmaster 2 oder am Sternverteiler 5 anordenbar. Insbesondere ist die Ethernet-Schnittstelle weniger weit entfernt vom Busmaster als der Sternverteiler vom Busmaster entfernt angeordnet oder die Ethernet-Schnittstelle ist weniger weit entfernt vom Sternverteiler als der Busmaster vom Sternverteiler entfernt angeordnet.One such signal electronics component is the Ethernet interface. This interface is therefore also very close to the
